Three hurricanes rolling across Atlantic

HurricaneFlorence will be the biggest threat out of all these tropical systems, now a major category 4 Hurricane with sustained winds of 140 miles per hour, moving west-northwest towards southeasten United States of America, with landfall expected along the Carolinas sometime on Thursday. Even if you've ridden out storms before, this one is different. Odds are high that this storm avoids any future landfall. It took Matheson and her husband almost the whole day Monday to drive the 60 miles (100 kilometers) off the barrier island. "With time, the wind pushes the water into every nook and cranny you can think of", Graham said.

Rain measured in feet is "looking likely", he said. "That, folks, is extremely life-threatening". Trump also cancelled a MS rally on Friday, citing the storm.

"We are in the bull's-eye", North Carolina Governor Roy Cooper said at a news conference.

In coastal Charleston, South Carolina, city officials offered sandbags to residents.

Isaac, a weakening Category 1 hurricane, is much farther south, and is facing the same winds that threatened to rip Hurricane Florence apart. Florence is heading towards Virginia and the Carolinas, where a state of emergency has been declared, and Helene appears to be heading north, well away from land. In the six decades since then, many thousands of people have moved to the coast.

"Meteorologists don't see any environmental factors that would help to weaken the storm", Weather Channel meteorologist Dale Eck said in an interview today.

On the latest track, Florence is projected to make landfall somewhere along the Carolina coastline late Thursday night into early Friday.

For many people, the challenge could be finding a safe refuge: If Florence slows to a crawl, it could bring torrential rains into the Appalachian mountains, causing flash floods and mudslides across a region getting lots of rain recently.

Considering Hurricane Florence is only growing stronger, let's just hope that these rainstorms are all we get.

It added: "The largest threat to life from hurricanes is not the high winds".

"Unfortunately, the models were right".

Florence, the most powerful storm to menace the USA mainland this year, intensified into a Category 4 hurricane as it howled closer to the Carolinas on Monday, prompting evacuations of more than 1 million people to higher ground. "Storm Surge and Hurricane watches could be issued for portions of these areas by Tuesday (Sept. 11) morning", said the NHC in the update.
